Three spectrophotometric methods were developed for the microdetermination of decamethrin in insecticidal formulations and in water. The methods are based on the hydrolysis of decamethrin with methanolic KOH to 3-phenoxybenzaldehyde; condensation of the hydrolysis product with 2,4-dinitrophenylhydrazine (2,4-DNPH), 4-nitrophenyl-hydrazine (4-NPH)
